Difficulty: EasyWireless Security Standards and Encryption Protocols

A technician is deploying a wireless access point and needs to select security protocols that protect against offline dictionary password-guessing attacks while providing modern, high-strength data encryption. Which of the following wireless security standards or mechanisms fulfill these requirements? (Select TWO.)

  1. WPA3-Personal utilizing Simultaneous Authentication of Equals (SAE)Answer
  2. Galois/Counter Mode Protocol (GCMP-256) encryptionAnswer
  3. C
    WPA-Personal utilizing Temporal Key Integrity Protocol (TKIP)
  4. D
    Wired Equivalent Privacy (WEP) utilizing a 128-bit static RC4 key

Answer

WPA3-Personal with SAE and GCMP-256 encryption are the correct security selections.
WPA3-Personal replaces the traditional WPA2 Pre-Shared Key (PSK) exchange with Simultaneous Authentication of Equals (SAE), which prevents offline dictionary attacks by creating ephemeral keys for each session. Additionally, GCMP-256 (Galois/Counter Mode Protocol with 256-bit key length) provides cutting-edge authenticated encryption for modern wireless networks.

Step-by-Step Solution

1
Identify the authentication protocol that prevents offline dictionary attacks.
WPA3-Personal uses SAE (Dragonfly key exchange) which eliminates passive offline dictionary attacks.
Legacy pre-shared key methods like WPA/WPA2-Personal rely on 4-way handshakes vulnerable to offline capture and brute-force cracking.
2
Identify the modern cryptographic encryption algorithm that provides authenticated data protection.
GCMP-256 is a modern 256-bit encryption cipher suite specified for WPA3.
TKIP and RC4 are deprecate/insecure legacy ciphers, whereas AES-CCMP and GCMP offer modern authenticated encryption.
